andlits principal i'equireinent is that it shall support a pile of books or magazines 111 such a Way'that access can be ha l to the upper ,or more books or magazines. Astslim vn the book bolder oonsistsof a revolmble turret I v ions slotted at 4, so that each connoartment open at its top and the compartments are which there arefonr at the respective sides of the turret The turretis revoluble aroundl thestantlarcl 5 and. there is a spring bolt (3 for looking it with any one of'these rows of Compartments in operative positionso that the other compartments are exposed fon'refilling. I

7, is a pedal by means of Whieh the bolt can be released.

wThe object in subdividing the book spaoe' into comparatively small iinit-s, as the com partinents 3, is to present fairly small piles books or magazines are Soboimclat one edge that when piled, the pile is much higher at that-edge than at the other, as can be'seen by reference to Fig. 7, #in which the bound edges are at the-'left-hand'side. Therefore paraiirely redueeti.

2', is a book holder. .Its form may vary arranged, one above the other inflrows oi;

surface of the pile and to the edge of one having compartments 3, separated by parti- I by reducing the height oftlne piles, the ,c ur Vat-ure at the top, while considerable, -15 com- ,There is paullel motion mechanism hav. ing a fixed end and a movable en the fixed end being shown at the left in h ig. 1. The parallel motion mechanism comprises links 9 and 10, and 11 and 12, one end of each of which is pivoted to the counter-balanced frame 13, and the other ends of the links 9 and 10, are pivoted t0 the fixed support 14, while the other ends of the links. 11 and 12, are pivoted to a carriage 15, which will be presently described. The pivots for the links are disposed in proper relation for insuring parallelism of the links. Applied to the parallel motion are two'belts 16 and 17, arranged to run over guide rolls 18 in the direction shown by the arrows in Fig. 1*, so that between theadjacent sides of the belts the books or magazines are carried.

19, is a counter-weight and its connections for balancing the weight of the parallel mo tion mechanism.

The carriage 15 applied to the movable end of the parallel motion, as has been described, has a tendency to descend and it is guided by a shaft 20 having rollers 21 that run in grooves or ways 22 applied to the standards 23.

, 24, are counter-weights applied to the carriage for supporting a part of its weight, but not sufficient-to overcome its tendency to descend by gravity. Projecting laterally from the carriage are rods 25 upon v.hich the feeder head 26 may slide. The feeder head 26 is reciprocated on these rods 25 by means of a link 27 and crank 28, formed on a shaft 29, journaled in the carriage and driven by gear wheels '30, from one of the feed rolls 31, which is driven by a sprocket chain 32 and by a sprocket-chain 33, the sprocket wheels for these chains being carried by the parallel motion and power being applied from the left-hand end of the parallel motion, as shown in Fig. 1 by means which are not illustrated. and down in respect to the feeder head 26, and it is shown as notched at 35 for the accommodation of the rods 25 which are tied together at their ends by the plate 37. The

feeder 34 drops behind the pile of books or magazines into position for raking or drawing one or any. required number of them at a time from the top of the pile. The set screw 36 affords means for limiting the extent to which the feeder 34 may depend from the feeder head 26. The rear end of the feeder head is provided with fingers, Fig. 9, which extend into the notches between fingers on the lower edge of the feeder and these fingers insure proper delivery of the books or magazines.

38, is a detector pivoted to the carriage at 39 and provided with a detent 49. The detent 40 is adapted to engage and disengage the teeth of a ratchet wheel 41 keyed to the shaft 20, fitted withtooth'ed wheels that The feeder 34 is movable up mesh with racks 44 carried by the standards 1 23. The detector is shown ."0 coinprise a rod 45 worki.:, through a guide 46 carried by the rods 25 and having at one end a roller to rest onthe top of the pile of books A and having at its 0' .er end adjustable connection by mear. of the adjusting screw and jam nuts 47 with the arm 48. There is a the guide 46 and a lug 50 projecting from the rod45 through a slot in the guide as .shown in Fig. 10. The purpose of this spring is to project the rod 45 throughthe guide and to thus tend to turn the detent 40 out of engagement with its ratchet wheel 41. Evidently the racks 44, pinions 43, ratchet wheel 41, detent 40, and detector 38, constitum a stop motion for arresting the descent of the carriage 15.

51, is a catch that may be employed for holding the carriage in elevated position, when desired, for example, when the machine is at rest or when the turret is being turned.

The carriage is fitted with what may be called a floating frame. There are brackets 52 and 53 and there are rods 54 which may work up and down through suitable openings in these brackets. These rods have adjustably screwed to them gates 55 and 56 having between them an opening 57 for the passage of the required number of magazines or books. v

.58, is a finger resting on the top magazine or book of the pile and it serves to position the floating frame, or more accurately, the opening 57 between the gates.

observed that the top gate has fingers 59 which are turned upward to guide books into the opening 57 60 are deflectors projecting fromthe brackets 52 and 53. 61 are springs which tend to exert pressure on the movable blocks 62 in which the feed roll 63 is 'journaled so as to draw the feed rolls 63 and 31, carried by the carriage 15 into contact. or more accurately, to draw the belts which. pass around. them into contact. It will, of; course, be understood that the belts are to be driven by the application of power, for example, at the left-hand of the parallel motion mechanism in 1, or in any other convenient way.

In use the compzzrtments of the turret are filled with piles of magazines or books and one row of compartments is presented to the reciprocating feederand detector. The carriage 15 is then freedffor example, by releasing the catch 51 and the carriage and all the parts carried thereby descend until. the detector 38 rests upon the top magazine or book of the pile A, which it does, not necessarily at the high part of the pile, but at any intermediate part of the top surface. The detector restingon the top magazine spring 49 interposed between a bracket on By reference to Figs. 6 and 7, it will be brings the detent 40 into engagementiwith'.

the ratchet wheel .41 and arrests the carriage.

Simultaneously with this, the finger 58 rests upon the-top edge of the pile of books-or" magazines and thus positions the-opening 57 between the gates for the passage of the vrequired. number of books ormagazines from the. top ofthe pile. The reciprocating feeder 34 then moves'towa'rd" the left, in 7, operates on the edge or edges of the top book or books and rakes orpulls'the sanie fforward. under the detectorthrough the space 57,. between the guide-rolls 63. and 31 into position betweenthe adjacent. sides of. the belts 16 .andl'i, which. carry it, or.them, forward along .ithe parallel motion fmeclmnism and deliver. it or them at'the left hand -slightly until it is in proper position for the; next" book feeding operation. Meanwhile the finger 58 rests uponv the book below and drawal from the top offthe pileof'maga-J zines or books, the detector drops Y to the next- 'boo.k or magazine of the pile andin-doing so releases the detent- 40 from the 'ratchet' wheel l1 and allowsthe carriage" to descend again properly. positions the opening 57 Bya repetition of the described operations the entire pile of books or magazines 'lS'fGd, not only from one compartment .111 fa .row,

' but successively from the various compartmentsj the openings 4 in which permit of the passage of the detector and reciprocating feeder. The parallel motionmechanism insures vertical movement of the carriage and proper aline mentfof the detector and.
